## Sample correlation matrix (heatmap)

### Description

Plot correlation of selected samples

### Usage

    plot_sample_corr_heatmap(
      data_matrix,
      samples_to_plot = NULL,
      sample_annotation = NULL,
      sample_id_col = "FullRunName",
      factors_to_plot = NULL,
      cluster_rows = FALSE,
      cluster_cols = FALSE,
      heatmap_color = colorRampPalette(rev(brewer.pal(n = 7, name = "RdYlBu")))(100),
      color_list = NULL,
      filename = NULL,
      width = NA,
      height = NA,
      units = c("cm", "in", "mm"),
      plot_title = sprintf("Correlation matrix of%s samples",
        ifelse(is.null(samples_to_plot), "", " selected")),
      ...
    )

### Arguments

`data_matrix` | features (in rows) vs samples (in columns) matrix, with feature IDs in rownames and file/sample names as colnames. See "example_proteome_matrix" for more details (to call the description, use `help("example_proteome_matrix")`)
`samples_to_plot` | string vector of samples in `data_matrix` to be used in the plot
`sample_annotation` | data frame with: `sample_id_col` (this can be repeated as row names) biological covariates technical covariates (batches etc) . See `help("example_sample_annotation")`
`sample_id_col` | name of the column in `sample_annotation` table, where the filenames (colnames of the `data_matrix` are found).
`factors_to_plot` | vector of technical and biological covariates to be plotted in this diagnostic plot (assumed to be present in `sample_annotation`)
`cluster_rows` | boolean values determining if rows should be clustered or `hclust` object
`cluster_cols` | boolean values determining if columns should be clustered or `hclust` object
`heatmap_color` | vector of colors used in heatmap.
`color_list` | list, as returned by `sample_annotation_to_colors`, where each item contains a color vector for each factor to be mapped to the color.
`filename` | path where the results are saved. If null the object is returned to the active window; otherwise, the object is save into the file. Currently only pdf and png format is supported
`width` | option determining the output image width
`height` | option determining the output image width
`units` | units: 'cm', 'in' or 'mm'
`plot_title` | title of the plot (e.g., processing step + representation level (fragments, transitions, proteins) + purpose (meanplot/corrplot etc))
`...` | parameters for the `pheatmap` visualisation, for details see examples and help to corresponding functions

### Value

`pheatmap` object
